Malltraeth Estuary and The Cob Loop
Anglesey
The Malltraeth Estuary fills the southwestern corner of Anglesey with wide tidal flats, saltmarsh and the distinctive raised embankment of The Cob, built by Thomas Telford in the 1820s to reclaim marshland. This 6.6km loop follows The Cob along the estuary edge before returning through the reclaimed fields and marshland, with big skies and long views to Snowdonia across the Menai Strait. The estuary is an important habitat for wading birds, with lapwings, curlews and redshanks working the mud at low tide, and the whole walk has a calm, expansive character that feels removed from Anglesey's busier coastal paths.
This is a peaceful dog friendly walk with a gentle, flat terrain that suits dogs of all ages and fitness levels. Off-lead potential is limited, however, as livestock grazes the reclaimed fields alongside the path and the estuary margins are sensitive bird habitat, particularly during winter months when overwintering waders are present. Leads should be kept on through the farmland sections. The estuary mud is accessible but very soft at low tide. The walk is exposed to prevailing westerly winds, so wrap up in winter. Parking is available in Malltraeth village, where the Joiners Arms pub welcomes dogs. A quiet, reflective walk rather than an adventure, best appreciated for its birdlife and big Anglesey skies.
